Answer:
4 hrs
Step-by-step explanation:
half of Jim Rollers time is 1.5 hrs, and half of John Brushs time is 2.5 hrs. The two combined is 4 hrs. Therefore, the answer is four hours.
This is basically finding the average of two numbers, and you can use multiple different equations to find the same answer.
3/2 + 5/2 =4
(3+5)/2 =4
5-3=2, then 2/2=1, 5-1=4
To solve this question, you just need to count all the probability of the options.
The probability that a pitch not over the plate is a strike is zero. So, P(A | D) = 0.
True. It is 0/0+20= 0
The probability that a pitch not over the plate is a ball is 1. So, P(B | D) = 1.
True, it is 20/20+0= 1
The probability that a pitch over the plate is a strike is 10:15. So, ...
Incomplete but it sounds to be true. It should be 10/10+5= 10/15 = 2/3
The probability that a pitch over the plate is a ball is 5:10. So, P(B | C) = 0.5.
Answer:
option A.
y = (1/2)x - 2
Step-by-step explanation:
It is given that, line that passes through the points (2, –1) and (6, 1)
Slope m = (y₂ - y₁)/(x₂ - x₁)
= (1 - -1)/(6 - 2)
= (1 + 1)/4 = 2/4
= 1/2
<u>To find the equation of the line</u>
Equation of a line passing through the points (x₁, y₁) and slope m is given by,
(y - y₁)/(x - x) = m
Here (x₁, y₁) = (2, -1) and m = 1/2
(y - -1)/(x - 2) = 1/2
(y + 1) = (x - 2)/2
y = -1 + x/2 - 2/2
= -1 + x/2 - 1
= x/2 - 2
The equation of the line is,
y = (1/2)x - 2
The correct answer is option A.
y = (1/2)x - 2
